Use Cramer's rule to solve the system of equations. If D = 0, use another method to determine the solution set.
-$$\begin{array} { l }
8 x - 9 y + 4 z = 0 \
- 4 x + 5 y + 5 z = 60 \
3 x - 7 y - 8 z = - 105
\end{array}$$
A) $\{ ( 8,8,8 ) \}$
B) $\{ ( 6,6,8 ) \}$
C) $\{ ( 5 , - 8 , - 8 ) \}$
D) $\{ ( 5,8,8 ) \}$
